Original application filed. February s, 1922, Serial No. 537,542. Divided and this application filed Maren 5, 1923; SerialiNo. 622,912.

To all whom it may concern:

Be'it known that I, HALTER S. RUNNnLs, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Drilling andRout ing Machines, of which the following is a specification.

This invention relates to improvements in drilling and routing machines.

My improvements of this application are especially designed by me for embodiment in sawing and trimming machines of the type shown'in my application for Letters Patent filed February 18, 1922, Serial No. 537,542, this application being a division thereof. My improvements are, however, adapted for use in other relations or machinesdesigned for other classes of work.

The main objects of this invention are:

First, to provide a machine of the class described in Whichthe operating mechanism is effectively housed and supported.

Second, to provide in a machine of the classdescribed an improved feed and drivingmeans.

Third,;to .provide in a machine of the classdescribedan improved frame structure in vwhichthe overhanging arm for supporting thevdrill spindle may be swung to one side to clear thetable.

Objects pertaining to details and economies of construction and operation will definitely appear :from the detailed description to follow. Y

I accomplish the objects of my invention the devices and means described in the following specification. The invention is clearly defined and pointed out in theclaims.

A structure which is a preferred embodiment of theinvention is clearly illustrated in the accompanying drawing 'formlng a part of this application, in which:

Fig. I is a right hand side elevationof a sewing and trimming machine embodying the featuresof my invention.

Fig. II is an enlarged detail vertical section on aline corresponding to line 2-2'of Figs. I and III, the parts being shown in full lines for convenience in illustration.

Fig. III is a detail view partially in'horizontal sect-ionon a linecorresponding to line 3&3 of Figs. I and II.

v In the drawing the sectional views are taken looking in'the direction of the little arrows at the endsof the section lines and similar numerals of reference indicate similar parts in all of the views.

Referring to the drawing, the base 1 is of suitable size to receive the pedestal 2 having a table 3 mounted thereon. The pedestal has a rearwardly projecting bracket arm 4 having an angled arm or, head 5 mounted thereon to overhang the rear portion of the table.

This arm or head 5 isof I-beamcrosssection, the upper and lower flanges or arms 6 and 7 thereof forming a channel like cham her 8 for the housing of parts as will be hereinafter described.

The head 5 is supported by the king or. pivot bolt 9 carried by the armd so that it may be swung to operative position as shown in Fig. I or swung to one side to clear the table, it being retained in its operative position by meansof the screw 10. The pin 9 engages a boss 11 on the head or arm 5.

The driving motor shown conventionally at 12 is mounted on the base 1 and is connected to a pulley on the shaft 13 by means of the belt 14:. The saw 15 mounted on the saw hanger 16 has suitable driving connection to this shaft as is illustrated and described in myapplication above referred to. As these features form no part of ,my present invention, they are not further described herein.

The work gauging and holding means is also illustrated and described in detail in my above mentioned application.

The drill and router spindle 17 is provided with a chuck 17 This spindle is mounted in a bearing 18 disposed in the channel 8 of the head 5. The spindle is provided with a pulley 19 connected by the belt 20 to a pulley 21 disposed at the angle of the head, the pulley 21 being connected by the belt 22 to apulley 23 vmounted on the bracket 4 of the'pedestal; This pulley 23 is connected by the belt 25 to a suitable pulley on the shaft 18,.thus-providing driving connections for the motor to the drill spindle. The pulleys'21 and 23. andthe belt 22 are arranged so that that the header arm5 may be swung on its pivot '9 without disengaging these driving connections.

Thespindle .17 iscarried by a sleeve 26 having a rack 27 onionejside thereof. A gear or pinion 28carried by the bearing member 18 meshes withthis rack. The gear pinion 28 is driven through the sprocket chain 2 one end o W i his con e t d to the spring 30 and the other to the cable 31 which is passed over the guide pulleys 32,

at the rear of the head, and 33 at the rear end of the pedestal arm a to the lever El i pivoted at 35 at the lower end of the pedestal. With this arrangement a downward movement of the lever feeds the spindle downwardly, the spring 30 automatically returning the spindle.

To limit the stroke of the spindle I provide a gauge screw 86 which is supported by the bearing member at the side of the spindle and parallel thereto. This screw is provided with a pair of adjustable stops 37 and 38 which coact with the pin 39 on the spindle sleeve to limit the stroke of the spindle. These drill spindle parts and the driving and feed connections are mainly housed within the channel of the head.

I have illustrated and described an embodiment or adaptation of my improvements which I find very practical. I have not at tempted to illustrate or describe other embodiments or adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.
